I think this is a problem with MixW, not the K3 firmware, which may have
inadvertently been correct due to the K3's reversal of its mode reporting.

In my version of MixW the radio type is set to Elecraft K2. There is no K3
option. The K2 option was a derivative of the Kenwood option, in fact it is
listed under Kenwood on the CAT selection dialog.

I was one of the first K2 owners to use MixW, many years ago. Unfortunately
my memory now is not very good, but I seem to recall that I originally had
the exact same problem as you with the K2 and MixW. I think that the K2 used
opposite sidebands to the Kenwood radios (and probably to the K3 as well.) I
emailed Nick, the developer of MixW, about it, and he fixed it in the next
release. So if my supposition is correct, the K2 option in MixW works right
for the K2, but not for the K3.

I think MixW needs to be corrected to work with the current K3 firmware,
which is now correctly reporting the data modes in software to correspond
with what is shown on the front panel. In the meantime, you might find that
switching to the TS-2000 option solves the problem. I very much doubt if
MixW uses any commands that are exclusive to the Elecraft radios, so this is
almost certain to be OK.
